Jag Cross Member Shock Mount 1966 F100

Mounting the Shocks



Putting the Jag suspension under the F100 is going well. Bought a suspension kit off ebay for under 200.00 shipped. The task is how to mount the shocks. The old upper shock mount location was on the inner wheel well. I have seen several ways to mount the shock. I could not find much info on the shorter shocks used buy our friends down under who have this down pat. 
The stock 1991 XJS shock specs are:
Compressed Length  11.875"  
Extended Length  18.250"  
Travel Length  6.375"     

Making a shock mount for the OEM shock would mean making a mount high on the chassis which I was trying not to do.

I found a shock in the garage that will work. Monroe shock part number 5804
Here are the specs:
Compressed Length  8.625"  
Extended Length  13.375"  
Travel Length  4.750"  

It is a way smaller shock and it has similar stroke. With 2" shorter stroke I must make sure that I have the upper mount positioned for optimum travel.

The problem with this shock is that it has the wrong set up on the bottom. It has the forked 2 bolt end on the bushing. I removed this by cutting one end off and pulling it through and removed the rubber.  I then cut the OEM shock to remove the sleeve.

Then I found that the rear shocks have an upper rubber bushing that fits perfectly inside the Monroe shock . I used it for the lower front shock. I placed the sleeve from the OEM shock in after the rubber went in.


Here the shock is in place on the bump stops. Now for the uppper mount.
Using a grinding disc I had to remove some of the thickness from both sides,( NOT SHOWN ) about 1/8 inch on each side for it to slip in the stock lower shock mount.


I found a lower shock mount left over from a project and cut to fit on the crossmember 

Notice the the lower shock washer had to be trimmed to fit inside the opening.


Shock mounted loose before finish welding it in.



Once welded in the suspension was removed for disassembly and rebuilding. The pics are for reference





The upper arms have a cast seam on the top and bottom. I thought it would be neat to remove the seam and emory the upper arm before sand blasting. Still have some finishing to do.

Ford Hubcaps and Wheel Vintiques Steel wheels Part 1

Project Disruptive by its' name, causes on to believe that we do not fit the mold.  Yes, going the shiny 20x12 Torque Thrusts may be tempting we are opting for the more traditional route. Looking at F100's on the inter-webs I found a truck to model after.  It uses stock Ford wheels and 57 Ford Fairlane Wagon Hub Caps, Dog dish, poverty cap, whatever you call them. Photo courtesy of Jerry Wassenaars1966-ford-f-100/HotRod.com  https://www.hotrod.com/articles/jerry-wassenaars-1966-ford-f-100/ The quest started looking for these hub caps..Just found some hub caps on Craigslist just like these.  I then searched for the best deal on wheels. Looking at some F100 Jag IFS posts and other F100 forums I decided to go with the Wheel Vintique series 62 - 15x7's up front with the standard 4 1/2 BS and the 15x8's with I believe the standard 4" backspace   They all arrived shipped for around $430.00. Now on to test fitting before painting. Very ...

1966 F100 ABS Headliner on the Cheap!

-
Image
Being Budget Minded AKA Cheap, I was now ready for the headliner. I did not want to put the traditional cardboard headliner in but I do not want to spend thousands on a custom interior. I saw someone had a 1 piece headliner for the f100's but shipping and the price was getting up there as well.  I found a local supplier for ABS sheeting. I opted for the 1/8 inch black sheet. It was around $40.00 a 4x8 sheet. I took my old cardboard headliner and traced the outline on the smooth side with a grey sharpie. The corners were a little difficult. I sprayed water on the corners and put a heavy  object on both sides in the sun. After some time I placed the flattened corners out and traced them as well. After cutting out all the pieces I started up the trusty propane heater. I gently warmed up the corners and when pliable I formed the hot ABS around my mig welder tank. A couple of tries and it was formed.   The back clips went back as the original....

1966 F100 style side wood bed floor- Can it be done?

-
Image
With the tubs widened 4 1/2 inches and the bed getting a coat of Raptor liner it is time for the wood bed.  The biggest thing to consider is how the wood will fit around the tubs and the gas tank filler tube location.  I  placed cardboard on the floor and just experimented with sizing until I was close. I allowed 1/2 " between boards. I found a local wood worker who was very helpful with the red oak.  The wood had checks and holes which I filled.  Cut grooves for the metal bed strips Stained with Danish Oil As you can see on the metal tubing I welded on tabs to bolt the rear, front and around the wheel wells. I made a trip to Dennis Carpenter to pick up some "Plain Steel" bed strips with no holes.  I bought the bolt kit and figured out where they needed to go. Using the mustang gas tank it puts the filler on an angle. I found that NAPA 1056 Gas Fill Hose was the ticket in fitting my Marine Gas filler. ...
